Ordered the caterpillar, there was our Mausi just four months ... and she loved the caterpillar IMMEDIATELY! (Contrary to my expectation, because I found them initially rather large and unwieldy, but what do I know of toys :))) now is the caterpillar Anytime and Anywhere! Otherwise I get problems to calm the small, if it is missing! And now during teething the rubber part is fully operational! We have already some other babies so 'infected' :) because the moms had also re-order the same :)))
